IMPROVEMENT vIN APPROACH-GATE.

The Schedule referred to in these Letters Patent and making pari: of thesame.

To all whom tit may concern:

, this specification- Figure 1 being an isometrical perspective of thegate as closed; y

Figure 2, a plan of the gate open. AFigure 3 is a 'view of thetriangular eye enlarged. i Like letters of reference designatecorresponding part-s `in'all the figures. v

-This invention has for its object a simple, cheap, and durable gate,one perfect in its action, and not liable fo get out oit order. I tbelongs to that class known-as approach-gates, which are opened byequestri-ans, or those riding in vehicles, without dismounting, andpossesses features of novelty and utility over all others now knowpy YOne important feature in my invent-ion consists in allowing the upperpiutle of the hanging stile of the gate to turn in a triangular eye in aplate attached to the main or back gatepost, which allows the frontstile of the gate to be raised, so as to release the lat-ch from itscatch when opening the'gate, and also serves to release it from thebevelen stops when the gate is to he closed.

Another important feature of my invention consists in the use ofelbow-levers pivoted to the oblique faces of the back gatepost,'whichvisset obliquely to` the roadway. The short suspended arms of theselevers gate by means ofv chains, and the long horizontal arms projectobliquely from their fulcrums to the axis of the roadway, or nearly so,so as to enable the rider to reach the short chains suspended from theircnds,'aud open the gate without dismounting.

A represents the gate.

13, the front gate-post.l

O, the main or back gate-post.- v l The hanging -stile D ot' the gate ispivoted at the bottom in the usual manner, and is provided with a pintleat the upper end, which turns iu an eye, c, iu a plate, t', secured tothe post C. Tliis eye is in the form ot' au equilateral triangle, withthe corners rounded, so as not to bind ou the pintle.

.E E represent the long arms oi' the levers, to the extremities of whichthe hand-chains b b arcattached. `To the rear ends are framed the leversS S, mak- 4 ving the proper angle therewith, as shown.

To the lower ends of these latter are attached chains ot' suitablelength, at e e, the other ends ofthe said' chains being secured to theupper bar of the gate,

as'at d el.

In 4the frout'part of the gate is pivoted lthe latch 9 which wipes intothe catch h, secured to post B.

G G are beveled stops, for holding the gate open, and

a a are the pivots on which the le vers E E are fulcrumed. Y

The Operation of the lifechanism. .The rider, on a load of hay, forinstance, drives un -der the end of the lever, and, taking hold of theend ot' the chain suspended therefrom, pulls down. This action, throughthe medium of the chain connected with the lever on the otherside of thegate, and to the top rail of the gate, lifts the forward stile, thusreleasing the latch ,from the catch, and, at the same time, pulls thegate open until the bottom ruil catches behind the beveled stop, whichholds it open. After passing through, a similar pull ou theothcr lever.llisengages the gate from the stop in the same manner that the latch wasreleased, and draws it shut, the latch wiping into its catch, as will beseen.

The action rcquiredin opening and closing, the gate is positive, anddoes not, in any degree, depend on gravity.

The triauguiar-shaped` eye in which the pintle turns I consider novel,and its action peculiar. When the gate is closed, the piutle rests inthe forward corner of the triangle, (see tig. 3;) but when the chainwhich connects the lever with thegate is drawn upon, it will be seenthat the strain, owing to the oblique position of the levers, is in thedirection of lthe side ot' the triangle. This draws the pintle to thelAnext adjoining corner.

\V hen the gate is to be closed, and the other lever is pulled, the`piutle passes `to the third'coruer, and releases the gate from the stop.

It will be seen that, as the 'lever-chains hang alymost directly overthev axis ot' the road, and not at one side, as in other gates o'f thisclass.. They may. at all times, and under all circumstances, be withinreach from a loaded vehicle, which they could not be if at the side ofthe road. Having thus described my invention, l What I claim as new, and`lesire to secure by Letters Patent, is- 1. The elbow-levers, composedofthe arms E E and S S, when arranged to operate vsubstantially as shownand for the purposes set foi-th.

2. In combination with the triangular eye c and `elbow-levers the mainor back post G, when the same isI set obliquely to the roadway, so as toform faces on which to'pivot the said levers, substantially as shown,and for the-purposes specitied.
